You nitrItes were probably "pegging" the test kit. So lowering of values would not yet register.

Before I started using plants, I would not add food when I added a fish especially that first fish. For a week or so. NitrItes would peg the api test kit (5ppm I think) for a couple of days then drop down to 0. After that I could add food with no spike. I just had to get through that initial spike.

Perhaps you need to stop adding the ammonia for a few days and let the nitrItes drop down. Then try the ammonia again and see if you are over the nitrIte spikes.

But then I don't use fishless cycleing so what do I know.
